Double-Spiral Herringbone Structure - Dense Mesh, Stable Load, Continuous Operation
The compound weave belt uses a double-spiral interlocked structure - two spiral coils per pitch unit instead of one. This doubles mesh density compared to standard balanced weave belts, producing a denser, more closed carrying surface with smaller mesh openings. YIYI Mesh Belt manufactures compound weave belts for baking ovens, washing lines, cooling conveyors, oil filtration systems, and heavy-duty industrial conveying - in friction-driven and gear-driven configurations, with soft wire, spring wire, and flat wire options.
A standard balanced weave belt uses one spiral coil per pitch unit - left-hand and right-hand spirals alternating across the belt width, connected by straight cross rods. The compound weave belt uses two interlocked spiral coils per pitch unit. The result is approximately twice the number of wire contact points per unit area, producing a measurably denser mesh surface.
This density difference has practical consequences. The smaller effective mesh opening allows smaller products to be conveyed without falling through, dropping, or deforming under their own weight. The denser surface distributes load more evenly across the product contact area - reducing contact pressure and surface marking on soft products such as dough, pastries, biscuits, and formed food items. It also provides better drainage uniformity in washing and air-cooling applications, where a coarser mesh would allow uneven water or airflow distribution.
YIYI Mesh Belt produces compound weave belts in three wire types and four structural configurations - each matching a specific application requirement. Wire type is not a preference; it determines whether the belt will perform correctly under the drive and load conditions of the intended application.
Standard wire condition for friction-driven compound weave belts. More flexible - easier to form into the tight double-spiral geometry. Used in baking, food processing, and washing line applications where the belt is driven by friction against the carrying surface or edge.
Required for gear-driven compound weave belts. Higher tensile strength supports the engagement stress of positive sprocket drive without progressive spiral deformation at the gear contact zone. Using soft wire in a gear-driven application causes spiral deformation after sustained operation - eliminated by specifying spring wire as standard for all gear-driven orders.
Round wire compressed to a flat cross-section (e.g. 1.5mm x 1.25mm from 1.0mm round). The flat face increases the wire-to-product contact area - reducing contact pressure per unit area on soft product surfaces. Used where round wire contact marks are unacceptable. Confirmed from actual YIYI production orders.
YIYI Mesh Belt manufactures gear-driven compound weave belts and the matched drive sprockets as one integrated supply. Belt and sprocket specifications are confirmed against each other before production begins - eliminating the pitch mismatch risk of sourcing belt and sprockets separately.
A first-piece running test - belt engaging the actual matched sprockets - is performed before mass production is authorised. The running test is video-documented and sent to the customer for confirmation. No batch is released without this confirmation. This applies to all gear-driven compound weave belt orders at YIYI Mesh Belt.
Based on YIYI Mesh Belt actual production records
YIYI Mesh Belt supplies compound weave belts with PTFE (Teflon) coating - dual-side or single-side. The belt mesh is produced and fully inspected first, then sent for PTFE coating before final packing. This is not a surface treatment applied during production - it is a dedicated coating process applied to the completed belt.
PTFE coating confirmed from actual YIYI production records - including dual-side PTFE for baking and food processing applications, with explicit requirement to leave adequate time for PTFE coating before final delivery date.
The following ranges are drawn from actual YIYI Mesh Belt production orders - not catalogue claims. All dimensions within these ranges have been produced, tested, and shipped to customers worldwide.
YIYI Mesh Belt is the only manufacturer in China with in-house stainless steel wire drawing capability for conveyor belt production. This means raw material quality, wire diameter precision, and tensile characteristics are controlled from the beginning - not accepted from an external supplier without verification.
Most compound weave belt failures occur at predictable points in the production or installation chain. Understanding the failure mode is the first step to preventing it.
The compound weave belt's double-spiral density and available configurations make it suitable across food processing, industrial manufacturing, and specialised conveying applications where a standard balanced weave belt would be too coarse.
YIYI Mesh Belt supports compound weave belt projects as OEM manufacturer and as replacement supplier. For OEM projects, drawing-based production with sample confirmation before batch release. For replacement projects, existing belt sample and conveyor system review to confirm the replacement matches the actual installation.
